Topic: Using SearchParameter and updating a resource

I'm using the following SearchParameter to eliminate duplicate Identifiers for a Patient resource. It works fine until I try to update that resource using the identifier as part of the PUT command with URL http://localhost:3111/myfhir/Patient?identifier=urn:uuid:555|26828F0386673. An error is returned

Can not create resource of type Patient as it would create a duplicate unique index matching query: Patient?identifier=urn%3Auuid%3A555%7C26828F0386673 (existing index belongs to Patient/391494aa-0cba-4e88-85c8-7539a5e9506f, new unique index created by SearchParameter/11d73d9c-b13a-4f70-9e7d-a7a916d80765)

If I use the id for the patient directly the update of the resource works fine. http://localhost:3111/myfhir/Patient/391494aa-0cba-4e88-85c8-7539a5e9506f.

Once I use a SearchParameter does that mean I can't use the identifier for the update? What am I missing?

It's worth noting that in the HFJ_IDX_CMP_STRING_UNIQ table the IDX_STRING column always has an entry like Patient?identifier=urn%3Auuid%3A555%7C26828F0386673 no matter if the SearchParameter expression is Patient.identifier or Patient.identifer.value

Thanks.

The SearchParameter looks like:

I've fixed my FHIR base URL, but I'm still getting "Failed to fetch API definition". This is a fresh HAPI deployment... can anyone help? Screen-Shot-2022-02-03-at-4.22.46-PM.png
